I'm kinda new into economy crashes, was a kid in 2008, is there a way to protect of it?
Skill. Knowledge. At your age, your biggest assert is your future earnings potential. The more employable you are, the better you will make iduring and after a downturn. In fact, the highest skill folks tend to even profit from hiccups in the economy.
This advice is from half a century ago. The times have moved on.
